6,100 ounces of gold extracted in the first 17 months.
Sonic sampling and well installation on a heap leach pad
Longyear used Sonic drilling to collect samples and install solution-enhancement wells on a Nevada heap leach pad. The work helped identify dry zones and inform leach-pad interventions.

- Heap Leach Pad
656 meters drilled in 39 shifts, intersecting within 2.1 meters of target.
Directional drilling reaches a paste-fill target in a single pass
Longyear completed a large-diameter paste-fill hole where borehole accuracy, casing requirements, and single-pass delivery were central to the program.

- Mine Development
- Paste Fill
2,300 meters drilled; wells completed to 250 meters; less than 1% hole deviation.
Dual-tube flooded reverse drilling supports mine water wells
Longyear used dual-tube flooded reverse drilling for mine water wells in the Pilbara, where ground conditions, discharge management, and active operations shaped the drilling plan.
